Thus, for example, if you want to factor the polynomial x 15-1, you can do this just by giving Mathematica the command Factor @ x^15-1 D; you do not have to know the fairly complicated details of how such a factorization is actually carried out by the internal code of Mathematica. Enterprise Mathematica; Wolfram|Alpha Appliance. Not an enormous problem, but I sometime use the ClearAll to find instances of my functions, and so this palette would simplify my actions, but not greatly if I need to do something else to get the different color. ]}, @online{reference.wolfram_2022_clearall, organization={Wolfram Research}, title={ClearAll}, year={2022}, url={https://reference.wolfram.com/language/ref/ClearAll.html}, note=[Accessed: 18-January-2023 While the mark is used herein with the limited permission of Wolfram Research, Stack Exchange and this site disclaim all affiliation therewith. ClearAll [Evaluate [Context [] <> "*"]] If you want to remove all symbols from the kernel so that Mathematica doesn't recognize them anymore, you can use Remove [] similar to the above two examples. Suppose I define a function, Now, just to do some sanity check, I define c as, and evaluate Integrate[Myf[y], {y, -1, 1}] to get, Now, even if I delete the c = 1 line, Integrate[Myf[y], {y, -1, 1}] still evaluates to. global ' * orNames ``.
